The device has these tech specifications:

North America:
4G LTE: 700/750/850/1700/1900/2100 MHZ (Bands: 1/2/4/5/13/17)
HSPA+: 850/900/1900/2100/AWS MHz (Bands: 1/2/4/5/8/10)
GSM: 850/900/1800/1900 MHz
4G LTE: 800/850/1700/1800/1900/2100/2600 MHz (Bands: 1/2/3/4/5/7/20)
HSPA+: 850/900/1900/2100/AWS MHz (Bands: 1/2/4/5/8/10)
GSM: 850/900/1800/1900 MHz

Are any of these supported by our networks?

It will definitely work on the gsm band with all zim networks. But you have to check if it isnt carrier locked. If it is locked you will have to get it unlocked to work on zimbabwean networks. Also you will only get 2G(edge) connectivity since none of our networks have hspa+ or 4G.

GSM will give 3g connectivity though, not just 2g
commented by Regular (1.5k points)
Thanks for the correction but how is that possible since gsm and umts(3g) are different network platforms. Check the wiki article on gsm and 3g
commented by Guru (57.6k points)
HSPA+ uses umts frequencies too - so while you may not be capable of HSPA+ speeds it will still get 3g speeds (HSPA+ is just a 3g extension)
commented by Regular (1.5k points)
Thats exactly why i think 3g wont work because to operate hspa+ some additional machinery would be needed by our service providers over and above normal 3g which is hspda. Zim networks only support hspda as i gathered from sources. This devices 3g is too advanced for our networks here.
commented by Guru (57.6k points)
HSPA+ protocols on the phone are backwards compatible with 3g cell towers HSPA+ is just an extension of 3g (in fact HSPA+ is basically a 3g protocol itself) so by design devices are designed to link at the highest/best available version of the 3g protocol

its like 802.11 a/b/g/n your router may support a specific only support the g mode and your wireless adaptor may support n but the devices were designed with backwards compatibility in mind as they use the same frequencies ultimately

It will work through backward compatibility like what Anthony is saying.
